3.10.7.6.1.6 T5CNTH – Timer5
Counter Register High Byte
The T5CNTH/L registers
provide direct access, both for read and for write operations to the 16-bit counter. The
T5CNTH register represents the upper byte of the counter value. To ensure that both the
high and low bytes are read and written simultaneously when the CPU accesses these
registers, the access is performed using an 8-bit temporary high-byte register (TEMP).
This temporary register is shared by all the other 16-bit registers.
See Accessing 16-bit Registers section for more details. Modifying T5CNTH while the counter is
running processes poses the risk of missing a compare match between T5CNT and the
T5OCR register. Writing to the T5CNTH register blocks (removes) the compare match on
the following timer clock.
